Working with C.

Reading a file into a void* datatype, void * v.
Have memory in a char* datatype, char * c.

Want to copy void* data into char* like you would two char*s, i.e.

char *a,*b; while (xyz) { *a=*b; *a++;*b++; }

I know I can do memcpy etc. but it needs to be this way because I'm also going to check the data in the void* byte/bit for byte/bit.

I'd also like to see what each byte or bit of void* is. How would I do this? I can't do v[x] or *v like I would a char datatype.

Then I need to compare the data between the void* and char* with memcmp.

PHP is by definition the best language ever made, but it's worse than Java and better than JavaScript.

>>61207114
Bitmask.
>>61207147
PHP can produce code rapidly. The only flaw is that it has too strict syntax. I wish someone would make a language like PHP, but more loose interpretation.

>>61207150
Someone help a brainlet like me understand this

I decided to learn how to program. I read K&R, C Primer Plus and C Programming: A Modern Approach and I still don't know what to do with what I've learned.

>>61207180
PHP is by definition the best language ever made. You can produce code in it faster and easier than any other language. But when analyzed you get the result of it technically being inferior to Java and superior to JS.

php is objectively best

>>61207176
javascript!

>>61207227
No, javascript is very very strict. The ideal language would be constructed with the design principle of, if it doesn't compile/run/work, it's the language's fault. So for example, a = b and a == b are syntactically identical and are evaluated based on context.

>>61207273
you dont even need semicolons in js

a = function() { 
   console.log("Hello") // oops forgot a semicolon!
   console.log("World");
}

//but it still works!
a();

But all the following will error:

And so on, and so forth. There's no language that does this.

>>61206734
of course it will. How are you building this bookmarking script? whats it meant to do?

>>61207356
so you want a language where you can smash your head on the keyboard and it still compiles and runs?

>>61207356
I forgot

console.log hello

>>61207370
Yes, in principle. It would be fun to work with, you would essentially only be constrained by your tpying speed since you wouldn't even need to bother with spellchecking.

>>61207273
>javascript is very very strict
JavaScript is probably the least strict language there is
>>61207356
>There's no language that does this.
When did you start learning your first language? 2 minutes ago?

>>61207370
So basically VB6.

>>61207436
Yes, but it's still very strict.

2 years ago.
Are there any?

>>61207447
Doesn't vb6 have some degree of syntax validation?

>>61207370
>smash your head on the keyboard
Don't say that in the mechanical keyboard thread

>>61207449
>>it's probably the least strict language there is
>Yes, but it's still very strict
Are you braindead?
>>61207356
>Are there any?
console.log() is how you output things to the console in JavaScript, just like how you use printf()/puts()/whatever in C, print() in Python, Console.Write() in C#, etc.
What's so hard to understand about that?

>>61207512
It's more strict than what it technically needs to be to be able to write code in it.

This is correct, and there's nothing directly wrong with it from the perspective of JS. But there are no languages with that feature in existence, which is sad.

>>61207370

>Smash your head on the keyboard and it still compiles and runs?
Brainfuck? I made a Brainfuck compiler in Ruby. It doesn't produce any errors except for an unmatched [ or ] character. Since every character other than the original 8 is considered a comment, you could smash your head into the keyboard and produce a valid program.

>>61207485
does that damage the keyboard or something?

Let's say I have a function that randomly will spit out a boolean so that my already threaded worker can pile it ontop of his job
Now, how is the best way to share data to a threaded function that will receive it without warning. I've always done a queue but that never felt right.
Just did some reading on namespaces, they seem like the holy grail to this type of thing or am i getting too excited?

Doing this in python 3.

def worktodo(barbool):
    while(True):
        if barbool:....
        else:....
        
t1 = threading.Thread(target=worktodo, args=([ ]))
t1.start()

def foo():
    for i in range(100):
        if random.randint(1,2)%2==0:return true
        else:return false

Yeah I know above code can be done more concisely, just making it easier to see it out and making example on the spot. Passing logic to a threaded worker like that is what i'd like to do cleanly.

I need more ideas, IDEAS ARE HARD D:

i hate javascript so fucking much

which would be faster?

void updateCount(int& count, int a){
    switch(a){
        case 0:
            count--;
        case 1:
            count++;
    }
}

or

void updateCount(int& count, int a){
    count += a * 2 - 1;
}

'a' must be an integer because it is the result of digitalRead() in the arduino (actually it is an ATtiny85).
I can't really test the result myself.

The next time you're gonna unload your jealousies and inadequacies online, here's a little piece of advice. Here's a little piece of advice, slick. Next time you're gonna go on the computer (mommy and daddy bought you a new computer!), you're going to unload your jealousy and inadequacies on somebody else, on a stranger? Just make sure you don't pick Sam Geno, the son of the Papa Geno Pizza empire. I've bought people like you. I've destroyed people like you.

It's nothing for me to call up my father, and have every pizza jockey in the nation have a photo of you, right above their oven. Thinking about you, my personal army of pizza makers. They'll put sauce on you. They'll lay you out. Swing you around in the air just like in the old movies. Then they'll destroy you. Piece by piece. Piece by delicious piece. Cheesy piece by cheesy crusty piece. They'll destroy you. That's option one. Option two is you can apologize to me. Just say you're sorry. Takes a big man to apologize, don't it?!?!

Second for D

>>61208362
lets start by slapping buzzwords together until we have a framework:

>statically typed

>>61208362
It's been tried several times. The most successful one by far was the feminist variant of c++.

Suppose I have a ternary that checks if int 'a' or int 'b' is greater than 10.


return (a > 10 || b > 10) ? true : false ;


I feel as if typing out " > 10" twice is rather redundant. Is there a way I could tie int 'a' and int 'b' together? as if I were trying to say:


return ((either a or b) >10) ? true : false;


I've done some googling around, but no luck.

>>61208394
For a start you should be able to express that as just

return (a > 10 || b > 10);

>>61208405
My question still stands. If it's not obvious, im a beginner.

>>61208389
can you link to the languages? or did they not get beyond a logo?

>>61207939
Probably the first one when compiled to a jumptable.

But you should always benchmark when optimizing anyway.

>>61208416
You mean in C? No. What you want is some kind of pattern matching and C doesn't do that.
With pattern matching, you'd have

match (a,b) with (10,10) -> true | _ -> false

And you see, this is not that much more compact than the C version.

is it a meme?

>>61208449
oops, didn't match the cases where a and b are more than 10.

>>61208449
I'm using java, but does it still apply?

>>61208394
nice bait but I'm compelled to answer

>return (a > 10 || b > 10) ? true : false ;
just write
>return (a > 10 || b > 10);

Now on to your question, write a helper function that takes in a predicate and a list of values and does it for you.

any(fun, list) { 
  for value in list { 
    if (fun(val)) { 
      return True; 
    } 
  }
  return False; 
}

return any(> 10, [a,b])

>>61208416
return(a>10 || b>10) is probably as much as you can simplify it in a c based language

>>61208416
There's no sensible way to do that in most commonly used languages. What you have already is simple and easily understandable, so keep it that way.

is lisp the way to job security?
unlike many other other languages lisp possesses natively(you don't have to define them yourself or implement them with assembly or some shit) many powerful features to define its own syntax.

if you get yourself installed in as a programmer at some company and write a system critical to company performance that works extremely well but no one could possibly understand but you(due to writing a lisp programming syntax which is readable to nobody but you), doesn't that make it so the company pretty much can't fire you unless they're prepared to make someone recreate everything you've done? as opposed to using another language where anybody else fluent in the language would be able to sit down and take over your job.

it's almost like a way to copyright/say "this software is mine" without even needing any law, so long as you can write up a mysterious enough syntax.

i wonder, does this say something good or bad about lisp?

i didn't think about it when writing that but just the situation itself would give you a lot of power beyond being layoff-immune, wouldn't it?

and since there aren't many business-involved people who understand lisp or even know what it is(probably) nobody who wasn't a programmer+knew lisp would even know you were designing such a system.

i realize that i'm a pretty scummy thinker. i can't help it.

User friendliness. Using HTML and CSS is very comfy in comparison to Qt and GTK. I believe Sciter has recongnized this but the dev decided to hold back technology and closed off the source. Now it's dead.

So I talked to a few Rust folks. This is because some of them are working on servo. I was suggesting why we don't fork servo (Atom shell is a fork of chromium). Servo is basically a gaming engine and it utilizes GPU far more than any other web rendering engine.

Alas, it turns out that HTML is not a cost free abstraction over the GPU. So I am back to square one. I'm thinking of designing a modern fork of QML/Qtquick that does not rely on JS.

Very, very true
C++ is a horrible language. It's made more horrible by the fact that a lot
of substandard programmers use it, to the point where it's much much
easier to generate total and utter crap with it. Quite frankly, even if
the choice of C were to do *nothing* but keep the C++ programmers out,
that in itself would be a huge reason to use C.

In other words: the choice of C is the only sane choice. I know Miles
Bader jokingly said "to piss you off", but it's actually true. I've come
to the conclusion that any programmer that would prefer the project to be
in C++ over C is likely a programmer that I really *would* prefer to piss
off, so that he doesn't come and screw up any project I'm involved with.

C++ leads to really really bad design choices. You invariably start using
the "nice" library features of the language like STL and Boost and other
total and utter crap, that may "help" you program, but causes:

- infinite amounts of pain when they don't work (and anybody who tells me
that STL and especially Boost are stable and portable is just so full
of BS that it's not even funny)

- inefficient abstracted programming models where two years down the road
you notice that some abstraction wasn't very efficient, but now all
your code depends on all the nice object models around it, and you
cannot fix it without rewriting your app.

Jesus christ some of you people need to learn to think for yourselves. Picking tools is really not that hard. In fact, I'm going to break it down into steps for you.

1. Search for things that do what you need done.

2. Figure out which ones are the best for YOUR USE CASE. Seriously, this step gets missed way too often and is the reason for the ravenous plague which is mapreduce.

3. Test things. Use your computer to see if the good ones actually work well for you.

4. Pick your favorite. There are probably no 'wrong' options left at this point. Just start working.

1) STL is stable and portable. You can break it, but only YOU can break it, by fucking misusing it. If you use it right -- that is, according to the documentation -- it doesn't break.
2) Boost isn't stable or portable but who the fuck uses Boost they are brainlets let me punch them C++14 has everything you need from Boost fuck off with your Boost it's a useless pile of crap.

#include <iostream>
#include <vector>
using namespace std;

int *fibArrIter(int n);
int *fibArrDyn(int n);

int main() {
    int n = 12;
    int arr_arr[2][n];
    arr_arr[0] = fibArrIter(n);
    
/*    for (int i = 0; i < 2; i++){
        for (int j = 0; j < n; j++){
            cout << arr[i][j] << ", ";
        }
    }*/

    return 0;
}
int *fibArrIter(int n){
    int arr[n] = new {1, 1}; // Sets first two elements
   
    for (int i = 0; i < n - 2; i++){
        arr[i + 2] = arr[i + 1] + arr[i];
    }
    
    return arr;
}

I am trying to rewrite a Python program with 2 different types of fib functions and print them out, however I am having trouble just assigning the output of the first function I wrote to a variable arr_arr.

Boost is known as std beta. Boost is more like C++ "insiders" and then a few years later gets directly implemented in C++. C++ and Boost share the same members in their committee

>>61211088
Yeah no shit, trying to find out why.

>>61211073
>int arr_arr[2][n];
This does not actually declare an array of 2 arrays of n ints each. It declares an array of n*2 ints, and gives you syntactic sugar to make it accessible as though it were an array of arrays.
If you want an actual array of 2 arrays, you'll need this:

int *arr_arr[2];

There's no way to specify the length of the sub-arrays this way, but that's alright; the compiler doesn't need to know the length of the sub-arrays, because it knows the sub-arrays will be allocated elsewhere. Which they are: they're allocated in fibArrIter.

If you write C++ that compiles and does something but does not conform to the standard, you are not writing valid C++. In fact, because the C++ you are writing is invalid, it is not C++. So if you criticize the behavior of the language you are writing, it's your fault for trying to compile that language with a C++ compiler.

>>61211102
>Boost is known as std beta.
I don't care what they call it, it's shit. I could call shit "rainbows and sprinkles" and it's still shit.

>>61211145
The std beta is valid C++ too. And it breaks left and right

>>61211164
>The std beta is valid C++ too.
Wrong. """""""The std beta""""""" does not conform to the standard. Therefore it is not C++ at all.

I saw this >>61211096 on fglt and was intrigued. How is GNU coreutils yes so fast? Can anyone write a faster yes than GNU in C?

>>61211173
>does not conform to the standard.
But the newer standard is going to include std beta anyway, what's the matter?

>>61211184
I tried to write my own as simple as possible
void main() {
while(puts("y"));
}
Which only gets 150mb/s, same as busybox yes.

>>61211193
The newer standard is not yet the standard and does not yet conform to the standard. Therefore it is not yet C++. Whatever it is is free to be as broken and self contradictory as it likes, but I guarantee that once it's C++, it will be stable (as in it will operate according to its specifications).

>>61211210
>but I guarantee that once it's C++
Yeah sure. It's magic after all

>>61211229
It's not magic, it's just logic. Once it's C++, it will be stable. I can say this with certainty because if it weren't stable, it wouldn't yet be C++. There has never been a version of C++ that was the standard and was also self contradictory or otherwise impossible to implement correctly. There have been versions of C++ that were self contradictory or otherwise impossible to implement correctly, but they were never the standard.

You can look at the source code; it's only 128 lines long.
It does use a god-awful GNU coding style, though.

#include <iostream>

int *fibArrIter(int n);
int *fibArrDyn(int n);

int main() {
    int n = 12;
    int *arr_arr;
    arr_arr = fibArrIter(n);
    
    for (int i = 0; i < n; i++){
        std::cout << arr_arr[i] << (i < n-1 ? ", " : "");
    }
    
    delete[] arr_arr;

    return 0;
}
int *fibArrIter(int n){
    int *arr = new int[n];
    arr[0] = 0;
    arr[1] = 1; // Sets first two elements
   
    for (int i = 0; i < n - 2; i++){
        arr[i + 2] = arr[i + 1] + arr[i];
    }
    
    return arr;
}

>>61211312
You assign memory for n int's.
int *arr defines a pointer to a memory location, in that line the memory region allocated by new is assigned to arr.

arr is a variable containing a memory address, to access its value you use the deference operator * or in case of a space with adjacent items (array) [].
*(arr) would be the same as arr[0] in this case.
*(arr+n) would be arr[n].

Any memory assigned through new has to be freed later by using delete. If it was assigned with the new[] operator you have to use delete[], otherwise for memory allocated with new use delete.
